Lock and Tech USA designs and installs burglar alarm systems that protect every entry point of your property with reliable detection, clear alerts, and optional professional monitoring. We install alarm systems for residential, commercial, industrial, municipal, and government properties, planning each system around your layout and demonstrating it to you before any final payment is collected.
Lock and Tech USA installs and configures alarm systems matched to your property and budget, working with both hardwired and wireless setups. Our main intrusion-alarm manufacturers include Honeywell, DSC, Bosch, and DMP, and we install other systems available on the market based on a discussion with you. If you already have a preferred platform, we work with it; if not, we recommend the right fit for your property.
Our systematic approach ensures comprehensive protection with minimal disruption to your property and daily activities, and we confirm the scope with you directly before any work begins.
We conduct a thorough property survey identifying all entry points, vulnerable windows, interior zones requiring protection, and environmental hazards. Our assessment considers property layout, occupancy patterns, and your specific security concerns to design optimal sensor placement and zone configuration.
Based on the assessment, we design a customized alarm system specifying sensor types and quantities, control panel capabilities, keypad locations, and backup power requirements. We balance comprehensive protection with budget, prioritizing critical areas while leaving room for future expansion.
Our licensed technicians handle every burglar alarm installation using professional-grade equipment and proper wiring techniques. Hardwired installations include concealed wiring through walls and attics for a clean, permanent result. Wireless systems use encrypted RF communication for flexible deployment without extensive wiring. All components are strategically positioned for optimal detection while maintaining a clean appearance.
After physical installation, we program the control panel with customized zone names, entry/exit delays, alarm responses, and user codes. Comprehensive testing verifies every sensor triggers properly, communication paths function correctly, backup power operates as designed, and remote access works reliably. We simulate various scenarios to ensure the system responds appropriately.
We finish every installation with an on-site walkthrough and tutorial covering arming and disarming, responding to alarms, adding and deleting user codes, adjusting settings, and basic troubleshooting, and we help set up the mobile app. You receive documentation including system diagrams, user guidance, emergency contact information, and warranty details.

Modern burglar alarm systems combine multiple detection technologies to create comprehensive protection against various intrusion methods.
Magnetic contact sensors on entry doors and accessible windows detect opening attempts. Recessed sensors mount inside door frames for invisible protection, while surface-mount sensors provide cost-effective coverage for windows and secondary doors. Heavy-duty sensors on commercial doors withstand frequent use while maintaining reliable detection.
Passive infrared (PIR) motion detectors monitor interior spaces by detecting movement through heat-signature changes. Pet-immune sensors ignore small animals while detecting human-sized intruders, and dual-technology sensors combine PIR and microwave detection to reduce false alarms. Strategic placement creates overlapping coverage zones that eliminate blind spots.
Acoustic glass break detectors listen for the specific sound frequency of breaking glass, protecting windows without individual contacts. A single sensor can cover multiple windows in a room, reducing equipment costs, and shock sensors detect impact attempts before glass breaks, triggering alarms during forced-entry attempts.
The central control panel processes all sensor inputs, manages system status, communicates with the monitoring station, and controls alarm outputs. Modern panels include cellular and IP communication backup, ensuring alarm signals reach the monitoring center even if phone lines are cut. Touchscreen keypads provide intuitive control, and multiple keypads at different locations offer convenient access throughout the property.
Interior sirens produce loud alarms that alert occupants and discourage intruders from remaining on the premises. Exterior sirens with strobe lights alert neighbors and help emergency responders locate the property. Voice annunciators can announce which zone triggered an alarm, providing immediate situational awareness.
Smoke and heat detectors integrate with the burglar alarm for added protection. Carbon monoxide sensors alert to dangerous gas, water leak detectors protect against flooding damage, and temperature sensors monitor freezing conditions in vacant properties. These integrated sensors maximize the protection value of a single system.

Professional monitoring connects your alarm to a central station where trained operators respond to alarm signals around the clock, significantly increasing the effectiveness of your system.
The central station receives alarm signals instantly when your system triggers. Trained operators verify alarms, attempt to contact you, and dispatch police, fire, or medical services as appropriate. Redundant communication paths including cellular and internet backup help ensure signals reach the monitoring center even during landline failures or deliberate line cutting.
Integration with your security cameras allows monitoring operators to view footage during alarm events. Visual confirmation helps verify genuine intrusions before emergency responders are dispatched, reducing unnecessary false-alarm responses.
Modern systems send real-time notifications to your smartphone whenever an alarm triggers or system status changes, so you can take action regardless of your location. App notifications complement central station monitoring, providing a redundant alert path.
Monitoring can extend beyond burglary to include fire, carbon monoxide, flood, and temperature alerts. Operators respond appropriately to each type — dispatching the fire department for smoke alarms, alerting you to water leaks before extensive damage occurs, and notifying you of freezing temperatures in a vacant property.
Modern alarm systems let you manage your security from anywhere and work together with your cameras for a stronger overall setup.
A smartphone app provides complete control from anywhere, including arming and disarming remotely, viewing current system status, reviewing alarm history, receiving real-time notifications, and managing user access codes. Remote control makes day-to-day management convenient without needing physical keypad access.
Alarm triggers can automatically record video clips on integrated cameras, documenting intrusion events. Cameras at entry points can capture images when the system is disarmed, creating a visual log of property access. This integration provides valuable evidence for investigations and increases the overall value of your security system.
Regular maintenance after a burglar alarm installation keeps the system reliable and functioning properly when it’s needed.
We recommend periodic system tests verifying all sensors trigger properly, sirens sound at full volume, backup batteries hold charge, and communication with the monitoring center functions correctly. The control panel logs test results, creating records that document system health and help identify developing problems before they cause failures.
Backup batteries maintain operation during power outages. Control panel batteries typically require replacement every 3–5 years, and wireless sensor batteries every 2–5 years depending on usage. We provide battery replacement so your system maintains backup power, and low-battery warnings alert you when replacements are needed.
Motion sensors require periodic cleaning to maintain detection reliability, since dust on lenses reduces sensitivity. Glass break sensors occasionally need sensitivity adjustments as buildings settle and acoustic properties change. Our technicians perform these calibrations to keep detection performing well.
Control panel firmware updates add features, improve reliability, and patch security issues; we monitor manufacturer releases and schedule updates with minimal disruption. Proper maintenance also reduces false alarms — we adjust sensor sensitivity, relocate problematic sensors, add bypass capabilities for specific zones, and provide additional user guidance addressing common false-alarm causes.
